ON Turn ON the servo.
OF Turn OFF the servo.
The arm system is set in local variable No. 99 upon successful completion of SVON.
Right arm system = 1
Left arm system = -1
Indeterminable = 0
Judgment is made based on the angle of arm 2.
Judgment is made on the basis of the angle of arm 2 after the arm 2 servo is turned ON.
This command sets the arm system immediately after servo ON and will not monitor the
arm system continuously.
[Example 1] SVON 1 Turn on the servo for SCARA axis 1.
[Example 2] SVON 110000 Turn ON the servos for linear movement axes (axes 5
and 6).

Optional Optional MOVP Position
number
Prohibited PE
[Function] Move the actuator in PTP mode to the position corresponding to the position number
specified in operand 1.
The output will turn OFF at the start of axis movement, and turn ON when the movement is
complete.
(Note) Movement to any position where target values for both SCARA and linear movement axes
are specified simultaneously is prohibited (“Error No. 421, SCARA/linear movement axis
simultaneous specification error”).
To perform any operation meeting the above condition, use a GRP command or set
different position data for SCARA axes and for linear movement axes.
[Example 1] MOVP 2 Move the axes to the position corresponding to position
No. 2 (200, 225, 150, 30).
(Note) In the case of a SCARA axis, the axis will move based on the value of all-axis parameter No.
47, “Default SCARA axis PTP acceleration” or all-axis parameter No. 48, “Default SCARA
axis PTP deceleration” if the acceleration or deceleration is not set by an ACCS (DCLS)
command.
In the case of a linear movement axis, the axis will move based on the value of all-axis
parameter No. 200, “Default linear movement axis acceleration” or all-axis parameter No.
201, “Default linear movement axis deceleration” if the acceleration or deceleration is not set
by an ACC (DCL) command.

With SCARA, the center of the tool-mounting
surface or the tool tip will move via PTP
operation (not linearly).
The movement locus will vary depending on the
starting position and end position of operation,
arm system, etc.
